The councils of two or more regional county municipalities which have not established a municipal court but to which the authority to do so has been delegated under section 9 may each adopt a by-law to authorize the making of an agreement regarding the establishment of a common municipal court, if expressly permitted by their respective agreements regarding the delegation of authority.
